LUMBER-WAGON.

SPECIFICATION forming part of Letters Patent No. 328,793, dated October 20, 1885.

Application filed November 15, 1883. Serial No. 111,890. (No model.) I

To all whom it may concern:

Be it known that we, WILLIAM LEONHARDT and JOHN H. LEONHARDT, of Waverly, Baltimore county, Maryland, have invented certain new and useful Improvements in Lumber- WVagons, of which the following is a specification, reference being had to the accompanying drawings, forming part hereof, in which- Figure 1 is a side elevation showing the operation of our improved lumber wagon. Fig. 2 is a top plan view of the same. Figs. 3 and 4 are detail views.

Like letters of reference mark the same parts in all figures.

Our invention relates to lumber-wagons; and

. it consists in the construction, arrangement,

and combination of the several parts, as will be fully hereinafter described, and specifically pointed out in the claims.

Referring to the drawings by letter, A are the front wheels mounted on front axle, B, and A are the rear wheels on rear axle, B. These are of ordinary construction.

Hounds a are attached to the front axle, and form, as usual, a continuation of the shafts. (Not shown.) The cross-bar of the hounds is seen at a, and the whole frame, consisting of front axle, shafts, and hounds, turns on pin a 0 are the front standardsmounted at the ends of front bolster, c, and O are the rear standards mounted on the rear bolster, c.

The coupling-pole is composed of two parts, D D, which telescope into and out of each other to lengthen the distance between the wheels, and are secured at any desired point by a pin or screw, d. The part D of the couplingpole is secured in any desired manner to the rear axle, and the part D to the front bolster, c, and rests on the cross-bar a.

F is a gear-wheel on the end of a shaft or drum, f, mounted in suitable bearings at:

tached to the front standards, and this gear meshes with a pinion, G, which is turned by a crank, g, as shown.

A pulley or sheave, H, is mounted at the top of each of the front standards, and over these pass cords or chains h, which are secured at one end to the shaft f, and at the other to an arm, I, of which there are two, one pivoted to each end of the bolster O, or to each standard 0 at k, as shown. A rod is journaled in these standards, and carries a roller, 2'.

Instead of the hounds, which are usually attached to the rear axle, a frame is used, consisting of side bars, M, and end bar, M, the latter being formed as a collar, m, at the center, and inclosing the part D of the couplingpole at this point, the joint being such as to permit the'pole to slide in said collar. Pivoted to the outer ends, a, of said cross-bar M are arms N, which carry a roller, N, in a manner similar to the arms I and roller 2', before described. This frame may be operated to raise the roller N by any desired means. The side bars, M, are dropped slightly below the level of the axle, for a purpose hereinafter described.

L is a roller mounted in bearings attached to the rear standard, 0, and are mounted so as to be substantially on a level with the top of the rear bolster, c.

P is a skid having rollers p, and attached by means of hook h to the rear bent end, m, of the bars M.

R represents the lumber.

O is a chain or cord connecting the bars I with the bars N.

The operation may be described as follows: The wagon being loaded, and it being desired to unload the same the skid P is placed in position shown in Figs. 1 and 2. The crank 9, applied to the shaft of the pinions G, is turned, rotating said pinion. and shaft f to rotate, winding up the cord h thereon, which causes the bars I to be raised, the lumber resting on the roller z being also raised until the portion shown in Fig. 1 is reached. The attachment, by means of the cord 0, causes the bars N, carrying the roller N, to rise simultaneously with the bars I and roller 2'. The inclination of the lumber causes its rear portion to rest on the roller 6, so that in this position the whole load will be supported on the rollers i, N, and L, thus rendering it an .easy matter to slide the whole load to the rear. When the front portion of the load in sliding rearward leaves the roller 2', it will rest on the roller N, and when it has passed that roller, and also L, it will rest upon and may be easily and gradually rolled down on This causes the gear F I the skid-rollersp. It will thus be Seen that the whole load of lumber may be placed upon 2. The combination, with alumberwagon, of the roller 6, pivoted bars I, roller N, pivoted bars N, the cord 0, connecting the bars I and N, and mechanism for raising the bars I, for the purposes set forth.

In testimony whereof we have hereunto set our hands, this 14th day of November, 1883, in presence of three witnesses.
